Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed November '7, 1907. Serial No. 101,126.

To all whom it may concern: ii

Be it known that I, ARTHUR GRETTON TOMKIES, a subject of Great Britain,residing at Westport, New Zealand, have invented new and usefulImprovements in Belt-Fae teners, of which the following is a specificaetion.

This invention relates to belt fasteners, and it consists in an improvedbelt fastener which is adapted for use on all classes of belts,

grips the full width of the belt without damaging the fabric therebyaffording great strength, is safe in use, and can be readily appliedboth to old and new belting. This belt fastener grips the ends .of thebelt as in a vise without damaging them thus insuring a durable joint. 7

The belt fastener comprises a preferably oblong lower plate providedwith vertical teeth on the two longer parallel edges, a slightly concaveupper plate of similar shape to but wider than the lower plate, andmeans for securing the two plates together so that the ends of the beltare gripped between them as in a vise, the teeth of the lower plateentering the belt near the ends thereof respectively. Various means maybe employed for securing the plates together two instances beinghereinafter described and illustrated. adapted respectively for smalland large belts.

The invention is illustrated in the accompanying drawings, in which thesame numer als of reference indicate the same parts, and Figure 1 is aplan view of the lower plate for small belts. Fig. 2 is a side view ofthe same. ig. 3 is an end view of the same. Fig. 4 is a plan view of theupper plate for small belts. Fig. 5 is a side view of the same. Fig. 6is an end view of the same.

position on the same. Fig. 9 isa plan view of the same.

Fig. 10 is a plan view of the lower plate for large belts. Fig. 11 is anend view of the same. Fig. 12 is a side view of the same.

Fig. 13 is a plan view of the upper plate for,

large belts. Flgldfi: is a side view of the same. Fig. 15 is an end viewof the same. Fig. 16 is a side view of the fastener for large belts inposition on a belt. Fig. 17 is a plan view of the same. Fig. 18 is anend viewof the same. Fig. 19 is a detail view of one of the nuts usedfor securing the plates of the fastener for large belts.

The lower plate (1). of the fastener is I sheet metal such as rolledsteel.

Fig. 7 is; a side view of the fastener for small belts in a belt. Fig. 8is an end view of formed preferably by stamping out from sheet metalsuch as rolled steel. It is preferably oblong in shape and is providedwith vertical teeth (2) formed on the two longer parallel edges. Theupper plate (3) is also formed preferably by stamping out from It is ofsimilar shape to but wider than the lower plate (1), is slightlyconcave, has its corners rounded, and has a flange 1) formed on each ofthe longer parallel edges. Strengthening ribs (5) see Fig. 13 are formedin the upper plate for large belts.

The means for securing the upper and lower plates together are asfollows. In the case of a fastener for small belts, (see Figs. 1 to 9inclusive) two or more eyes .(6) are formed integral with a centralflange (7) on the lower plate (1) and these eyes (6) are adapted toenter openings (8) formed in the upper plate (3), a pin (9) being passedthrough the eyes (6) to secure the plates (1) (3) together. In the caseof a fastener for large belts, (see Figs. 10 to 19 inclusive) threadedpins (10) are secured in the central 7 flange (1 1) of the lower plate(1) the pins being screwed into the flange and their heads (12) beingriveted underneath the flange. These pins are adapted to enter openings(13) in the upper plate (3) which are larger in diameter than the pins(10) in order that the extensions (14) of the special nuts (15) see Fig.19 preferably used which are screwed up on the pins (10) to secure'theplates together, may pass through the upper plate and be screwed down onseats (16) formed in the central flange (11) of the lower plate (1). Thepeculiar construction of these nuts (15), gives a greater hold andlessens the pro ection of the nut heads above the upper plate (3).

To increase the holding power of the belt fastener, especially forrubber belting, the upper plate (3) may be provided with a series ofdownwardly struck teeth (2) on the lower plate (1') and adapted toalternate with them.

The belt fastener is operated as follows. The lower plate (1) is driveninto the under surface of the belt close to two adjacent edges (17) (18)thereof, and the upper plate (3) is placed on the upper surface of thebelt over the lower plate (1) and secured tightly by the securing means,the flanges (4) of the upper plate lying on the belt a little beyond theteeth on the lower plate (1).

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A belt fastener, comprising a lower flatplate having its two parallel edges turned up at intervals to formvertical teeth, a substantially concaved upper plate wider than the saidlower plate, said teeth being adapted to extend into the cavity, andmeans for securing the two plates together with the ends of the beltbetween them.

2. A belt fastener comprising a lower flat plate having a row ofvertical teeth on each of tWo of its edges, a longitudinal central 15flange formed integral with said lower plate,

l l l threaded pins secured into and riveted below said tlange, aet'ineaved upper than said lower plate and provided with holes for saidpins, above said p plate wider and nuts seeured on said pins upper plateso as to hold the 20 lates together with the ends of the belt betweenthem.

In testimony whereof l have signed my name to this specification in thepresenee ol' two subscribing witnesses.
